Different materials have different application fields. The die-cutting materials made of PET are also widely used in the industry. Today, Wantai will let you know the essential difference between the functions of PET protective film and PET release film. PET protective film PET protective film is coated with a layer of cross-linked polyacrylic resin as the adhesive on the basis of the original film, and then several special additives are added to prepare and debug. Glue is colorless and transparent, soft, good adhesion performance, high temperature resistance, low temperature resistance, a wide range of protection for various boards, and can be used to protect the surface of different materials. PET is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields. Features: Good weather resistance, high temperature resistance of 100-150 degrees, good hardness and smoothness; Disadvantages: Cannot be used on products with angles or corners. PET release film PET release film is an industrial material, also called silicone oil film, because of its strong adsorption capacity, it is often used for anti-static. The substrate is PET, the thickness is from 25um to 150um. The characteristics of PET release film: 1. Good stability, smooth and clean surface, no color migration, no scratches, no particles and other defects. 2. Produced in a 10,000-class dust-free workshop, with high cleanliness 3. Environmental protection and low static electricity. Moderate hardness, good flexibility 4. Uniform coating, good release force stability. PET release film has high transparency, non-toxic and odorless, high tensile strength, good stiffness, anti-burning, not easy to break, electrical and optical Excellent performance, good oxygen and humidity resistance, cold resistance (-70 degrees), heat resistance (+200 degrees), corrosion resistance, and stable shrinkage. The use of PET release film: used in the new energy industry, optical industry, electronics industry, mobile phone industry, computer industry, etc. It has a wide range of applications, such as bronzing film, aluminized film, printing film, packaging film, packaging materials, composite materials, laser anti-counterfeiting composite film, drawing paper, electrical insulating materials and capacitors.
